Utilizing json_encode() in PHP to store an array in a file, then leveraging JSON.parse() in JavaScript on the client side to read the json encoded file and pass it as an array to a sorting algorithm:
The result of my json_encode() operation in the output file: ["1","96","32","33","4","48","74","19","23","43","8","8","46","36","92","81","81","64","26","96","82","85","80","24","61","4","46","32","68","11","63","14","98","20","66","17","28","58","32","16","33","47","80","94","5","68","35","28","24","85","38","12","79","57","6","47","18","15","34","18","91","63","67","73","86","16","71","29","14","79","18","10","97","29","1","97","72","92","42","19","25","76","38",...
After applying JSON.parse(), I receive my array back in a variable
unsortedArraywith:Index: 0
Value: 1,96,32,33,4,48,74,19,23,43,8,8,46,36,92,81,81,64,26,96,82,85,80,24,61,4,46,32,68,11,63,14,98,20,66,17,28,58,32,16,33,47,80,94,5,68,35,28,24,85,38,12,79,57,6,47,18,15,34,18,91,63,67,73,86,16,71,29,14,79,18,10,97,29,1,97,72,92,42,19,25,76,38,25,21,37
However, upon running it through a sorting algorithm like Bublesort (acknowledging it's not the most efficient), the output seems unusual:
[0] => Array
(
[0] => 1
[1] => 1
[2] => 10
[3] => 11
[4] => 12
[5] => 14
[6] => 14
[7] => 15
[8] => 16
[9] => 16
[10] => 17
[11] => 18
[12] => 18
...
...
[84] => 97
[85] => 98
)
I invoke the sorting function along with the input this way
bubleSort.apply(this, unsortedArray);As displayed above, the data is not fully sorted; everything except certain numbers (1, 4, 5, 6, and 8) are arranged. This behavior puzzles me.
Update:
The $jobRetParam contains all results from another page, which serves as an output of JavaScript code sent using POST to the site via this piece of code:
$jobRetParam = $_REQUEST['results'];
The $allOutputVarPath variable is initialized here:
$allOutputVarPath = array();
$i = 0;
foreach ($allOutputVar as $key => $values) {
foreach ($values as $key => $value) {
if ($key == 4) {
$allOutputVarPath[] = array($value => $jobRetParam[$i]);
$i++;
}
}
}
The $allOutputVar originates from a Database where $key == 4 represents the $value holding the path for use in the $path variable within the subsequent loop. The statement $jobRetParam[$i] is elaborated right after the "Update" section, assigning each $value with its corresponding results.
I possess extensive code, but it ultimately boils down to this when encoding to Json:
foreach ($allOutputVarPath as $key => $values) {
foreach ($values as $path => $fileContent) {
$writeSuccess = wrtieToHDD($path, "w", $fileContent);
}
}
Here's a sample of
$path => $fileContentutilized as input in thewrtieToHDD()function for encoding the$fileContentintoJson.
$path: [.../sorted2.txt]
$fileContent: Array ( ... )
And here's the wrtieToHDD() function:
function wrtieToHDD ($destination, $fopenMode, $content) {
$handle = fopen($destination, $fopenMode);
// checking if $content is an array
if (gettype($content) == "array" or "object") {
// encode as json
$content = json_encode($content);
}
// writing into the file
$writeContent = FALSE;
if (flock($handle, LOCK_EX)) {
fwrite($handle, $content);
fflush($handle);
flock($handle, LOCK_UN);
$writeContent = TRUE;
}
fclose($handle);
return $writeContent;
}
